My final lecture in the Celts & Romans series was given as the Alderney Society’s Mendham Lecture on 9th July. This time I gave an update on our ideas about Roman Guernsey and Alderney, following on from the previous lecture which had covered familiar ground. It was also the first chance to discuss the ‘new’ find of 500 sherds of first and second century pottery from Longis Common which indicate an early military presence there.
